TROLLEY-POLE HEAD.

Specification of Letters Patent. Patented lay 30, 1922 Applic'ation filed January 10, 1922. Serial No. 528,211

To all whom it may] concern;

Be it known that I; VINonNzo Snoconn, a subject of the King of Italy, residing at Johnstown, in the county of Canibria and State of Pennsylvania, have invented certain new and useful Improvements in Trolley- Fole Heads, ofywhich the following is a specification.

The present invention relates to improvements in trolley pole heads and includes mechanism which will reduce to a minimum possibility of the trolley wheel leai inp; the wire.

A. principal object of this invention is to equip a trolley pole heaidwith' mechanism which will guide the trolley wheel back into engagement with the wire, if perchance the latter should be displaced, the ineihanisin being so constructed and arranged that it will in no way interfere with the normal functioning of the trolley pole.

Another object of the invention is to so Fig. 3 is a vertical sectional view of the device Fig. 1 is a vertical sectional view taken on the lin 4l-4t of Fig. 3 looking in the direction of the arrow; v

F 1g. 5 1S a sectional View. taken on the line I 5-5 of Fig. 1-;

Fig. 6 is a side elevational View of the trolley head per se;

Fig. 7 is a sectional view ofone of the guide housings illustrating the manner of mounting th guide therein:

8 is a detail enlarged sectional View taken on the line 8-8 of Fig. 2 illustrating to advantage the manner of mounting one of the guide abutment blocks, and

Fig. 9 is a sectional View of a modified form of guide housing showing a guide mounted therein.

Inthe drawings, in order to illustrate the application of this invention a portion of a trolley pole A is shown which may be of the usual or any desired configuration. The upper end of the trolley pole is equipped with a head 9-which preferably is detachably mounted on the pole and terminates in a forked upper end which einbodies branches 10. Each of said branches is equipped with" a: spring pressedY-shaped arm 10 the furca tions of which are engaged with feet 11, said feet being formed on a washer 12. As illustrated to advantage in Fig. 5, the feet 11 are offset frorn the'plan of the washer 12 and are carried directly within one of the branches 10 while the washer per se tends beyond the inner face of the branch. An axle 13 extends through the washers 12 and also through the branches 10 of the trolley head. are reduced and screw threaded, as indicated at 1 1 and project appreciably beyond the" branches 10. The axle 13 carries a trolley wheel 15' which niay be of the usual or any desired configuration. The hub of this wheel is embraced on both ends by the washers 12 thereby retaining the wheel centrally on the branches 10 and permitting the wheel to be flexed laterally in either direction for an obvious purpose;

Guide members are proyided one of which is mounted upon each of the branches 10 of the head 9. Each of said" guide members consists of a guide housing 16'which has a:

rib 17 formed on its inner faceythe rib complernenting the configuration of its branch 10 and. being snugly engaged therewith to prevent relative movement between the branch and housing. Each housing 1s sl1dably mounted upcn' the reduced end 14 of the axle 13 and has a segmental recess 18 formed therein which receives one end of a guide 19. A' guide 19 has anopening formed inits inner end which receives one of the re duced ends 14 of the axle, as shown in Fig.

7. The guide is normally held against one wall of the recess by the expansive action of a coil spring 20, one end of the latter being convoluted on an arcuate rod. 21. This rod is provided with a screw threaded end which engages the guide while the opposite end Th outer ends of the axle semi-circular passage-way 22. The opposite end of the spring 20 extends into the passage way 22 and has its'terminal convolution engaged with the end wall of the passage-way. Each guide has an abutment block 23 mounted on its inner face, the block having a groove extending longitudinally therethrough which receives a tongue 24 formed on the inner face of the guide. Each block carries a bolt 25 the latter having a screw threaded shank which projects through a slot 25' formed in the guide. A thumb nut 26 is mounted upon the threaded shank of the bolt. Preferably the inner face of each of the abutment blocks 28 is rounded and has its lower terminals in close proximity to the periphery of the wheel 15 to thereby facilitate engagement of the trolley wire with the wheel. A. portion of the lower end of each abutment block is extended to lie between the. trolley wheel and the inner face of its housing 16. It is apparent that the abutment blocks 23 may be adjusted when desired to take up wear, conform to different sizes of trolley wheels or to permit replacement should they be mutilated or otherwise rendered unsuitable for use.

In order to close the recess 18 and prevent the entrance of extraneous materials thereinto, a closure 27 is provided which has 1 is secured to the guide 19. Consequently,

the closure will move in its entirety with the guide. .However, the closure is of sufficientlength to at all times insure complete covering. of the recess 18 immaterial of the position of the guide.

'In use of this device it is apparentthat the trolley head is engaged with the trolley wire in the usual manner by permitting the guide members 16 to pass upwardly and straddlethe trolley wire until the latter en gages the wheel. 15. In view of the arrangement of the guides 16. it will be apparent that accidental displacement of the trolley wire will be reduced to a minimum.

If the wheel. is disengaged from the wire, there is little or no'possibility of the trolley pole gravitating to a point where thewire' would clear the upperterminals of the guides. However. even. should this conditionexist reengagement of the wire will be greatly facilitated-in an apparent manner. By permitting movement of the guides in their housing, it will be appreciated'that should an object contact therewith which is disposed at an angle to the path of movement of the trolley pole, the guides would be fiexedrearwardly to permit the object to pass thereover without mutilating the guide members or without in fact disengaging the trolley pole from the wire. As soon as the object has been passed, the guides will be returned to their normal positions by the expensive action of the springs 20. It is apparent that construction of the device is such that access may be gained to any part thereof conveniently and quickly so that repairs may be made thereto without undue delay. The mechanism may be made of wood, metal or other suitable material.

If desired, the trolley wire guides may be mounted so as to permit movement thereof in either direction thereby especially adapting the device for use on car lines where the car is not turned around at the terminal but the trolley pole thereof merely reversed. This form of the invention is illustrated in Fig. 9 wherein a guide housing 16' is provided which has a recess 18 formed therein. This recess communicates with both ends of a passageway 22. A circular rod 21 is movable through the recess 18 and passageway 22 and has fixedly mounted thereon a guide 19. I 1

The guide 19' is of the same construction and is mounted in the housing 16 in the same manner as the guide 19 is mounted in the housing 16. The rod 21has a pair of springs 20' convoluted thereon one being arranged on each side of the guide 19'. These springs engage an abutment 29 which is arranged transversely through the passageway 22 andisfixed to the housing 16. Pressure on the guide 19 urges the rod 21 through the abutment 29 thereby compressing one of the springs 20 depending upon the direction of movement of the guide. As soon as pressure is released from the guide the latter will be returned toits normal position by the expansive action of the compressed spring. a Various changes maybe made in this device especially in the details. of construction, proportion and arrangement of parts within the scope of the claims herewith appended. 7
